ISIS is the result of our mistakes in the past can't be fixed overnight, that's why the world powers need to set a long term plan and in the mean time they should help the Syrian and Iraqi government with intelligence and air strikes like crimsonghost suggested.. and by the long term plan I mean some kind of cultural improvement, teaching those people that they need to let go of Islamic extreme beliefs and get them more civilized and open minded
I think the U.S. is doing what they can against ISIS. This is a global problem however, not just affecting the United States and middle Eastern countries. It is something that the entire Western World needs to be concerned about, as they recruit people from other countries into their mad, mad movement. Personally, the problems in Syria seem much worse than the issues of ISSIS currently.
